If you never had a PEF license or an RF protect license applied to a controller, the controller will be missing parts of the configuration related to those licenses. Any controller you want that license to be applied to needs to be rebooted. If you are adding licenses to a controller that already has that type of license, you don't need to reboot.

If have centralized licensing enabled on two controllers and you don't have the PEF license, you need to apply it to the master controller and reboot both controllers. If you already have PEF licenses applied and the controllers have been rebooted, BUT you need to add more PEF licenses, you can just apply it, and the totals will be updated without you rebooting the controllers.

If adding PEF or RF Protect license to any controllers that have never had them, all will need a reboot.

Adding additional PEF and or RF Protect licenses does not require a reboot.

In our specific scenario, we have trial AP, PEF and RF licenses applied. All expired and I have extended the licenses.

PEF and RF have the Enabled flags. The AP license has Enabled and Reload. Do I need to reload both of the controllers, and I am assuming the recommendation is Standby first and then Master with centralised licensing?
